“Don’t stab us in the back!” said an emotional Eichen as he returned to his two-story attached home on Beach 120th St. after two months living in a hotel room and a senior home.

He bristled with anger at congressional apparatchiks who callously delayed the first hurricane relief package last week — then did an about-face and kicked the can down the road by promising a Jan. 15 vote on $50.7 billion in aid.

“I earned that money,” said Eichen, a retired mechanical engineer who dodged Nazi U-boats in the Atlantic during World War II when he fixed boilers aboard ships carrying war supplies to U.S. troops in Europe and North Africa.

“We’re standing on the shoulders of our family,” Eichen said with tears welling in his eyes. “We wouldn’t be here without them, we couldn’t survive without them, they were fixing this place up 24/7 so we could come back home.”

As his wife Yetta, a homemaker, stood proudly behind her walker, Eichen held himself up high on his two canes beside a U.S flag and told how their 57-year-old daughter Fran McCabe, 61-year-old son Richard, nine grandchildren and a gaggle of friends and neighbors helped gut and rebuild their home.
